Question:
My wife has to come back to London from Pakistan. I cannot afford to
go and bring her here. Can she travel for 8 hours on her own?

Some scholars give the permissibility if a woman travels with a
reliable and trustworthy group of people, as is the case when one
travels by air. This is after one has tried ones uttermost to arrange
for her travel with a mahram, and there is obvious need or benefit in
the trip.
